摘　　要：河南开普化工股份有限公司利用烧碱生产中副产电解氢作为氢源,进行了邻硝基苯甲醚催化氢化法还原制取邻氨基苯甲醚的扩大试验,在催化剂用量1%、反应温度130℃、反应压力1.6MPa的优化工艺条件下,邻氨基苯甲醚的转化率平均在99.3%以上,为进行工业化生产的设备设计、工艺探索提供了有力的保证。Expanded experiment for synthesis of o-aminophenol methyl ether from o-nitrophenol methyl ether by catalytic hydrogenation using by product electrolysis hydrogen from caustic soda production in our company as hydrogen source are carried out in our company. The optimal conditions are as follows : the consumption of catalyst 1%, reaction temperature 150 ℃ and reaction pressure 1.6 MPa. The yield of o-aminophenol methyl ether is above 99.3%. The experiment provides a strong basis for the equipment design of industrial unit or the exploration of process technology.
